You may not like guns. You may choose not to own one. That is your right.
You might not believe in God. That is your choice.
However, if someone breaks into your home at 3AM the first two things you are going to do are:
1) Call someone with a gun.
2)Pray they get there in time." - A wise man

You should go to the range an try as many of them as you can. I don't have any experience with CZ, but the other brands should be great choices for a 9mm. I have a Glock 19 and a Kahr PM9 and they are fantastic guns. I usually carry the PM9 due to it's smaller size and weight.
